Catalytic Converter

What is a catalytic converter?


A catalytic converter converts the harmful exhaust gases produced by the engine into less harmful emissions before they leave the vehicle's exhaust system.

The catalytic converter looks similar to a muffler. It is typically a stainless steel housing with a ceramic honeycomb inside that is impregnated with platinum, palladium, and rhodium. These elements help clean up harmful exhaust gases that otherwise would be expelled from the tail pipe.

It is common for a four-cylinder engine to be equipped with one or two catalytic converters, while six and eight-cylinder engines can have up to four.  

How does the catalytic converter work?


The catalytic converter has multiple sections, commonly referred to as beds. Each contains specific catalyst elements that work at a temperature of at least 400 degrees F to promote specific chemical reactions. This converts harmful CO, HC, and NOx exhaust gases into less harmful CO2, H2O, and N gases that are released from the vehicle's exhaust pipe.

The first section of the catalytic converter is called the reduction bed and is coated with rhodium. It is called the reduction bed because its purpose is to reduce the NOx gases back in to harmless nitrogen and oxygen.

The next section of the catalytic converter is the oxygen storage bed, which is coated with cerium. Its purpose is to maintain an ideal level of oxygen for use by the rear of the converter. It does this by storing and releasing the oxygen that gets released from the reduction of NOx in the previous reduction bed.

The oxygen is then available for use in the final oxidizing bed, which is coated with platinum and paladium. The purpose of the oxidizing bed is to complete the combustion of CO by adding oxygen. The oxidizing bed also uses oxygen to burn any of the raw HCs that still remain in the exhaust gases.

Natural remedy : Activated Charcoal

Charcoal is one of the most disregarded products at home. We only see the need for it when it is time to set fire for Banku.
However, if you really need first aid, charcoal is something you need to have on you all the time. You might not know this but it is one of the most medicinal products you can have at home due to its poison extraction ability.
In case you never gave it much attention, this is the time to do so. Here are *13* benefits of charcoal you never thought about.

1. Preventing Odour
Does your shoe smell bad? Just get some charcoal & put it in them. Do you have any bad smell in your room? Drop some charcoal where you suspect the smell could be coming from. Does your fridge or freezer smell? Put a piece of charcoal in it. Do you have strong body odour? Just make a powder out of charcoal & use.
Charcoal is very good at getting rid of bad smell. Ever wondered why your parents always scooped out the ash from the coal pot to pour in the hen coop or toilet before sweeping? That was to get rid of the odour.

2. Keeping Food Fresh
If you want your vegetables to be fresh all the time, just make a solution out of charcoal & leave your vegetables in them. Thank us later.

3. Removing Toxins From Food
These days, people complain about the use of fertilizers on plants & vegetables, making them unwholesome & poisonous. If you have charcoal, you don’t need to worry about this. All you need to do is leave the vegetables in a charcoal solution overnight & it’ll take care of the toxins. If you suspect any food contains too many chemicals, just drop them in a charcoal solution for some hours & you’re good to go.

4. For Teeth Whitening
If you want to whiten your teeth, pay no attention to all these adverts on whitening chemicals & technology. Just get yourself some charcoal & grab hold of a plantain stalk. Make a powder out of the charcoal, mash the tip of the plantain stalk, dip it into the charcoal powder & brush your teeth with it for a week.

5. Restoring Soup That Went Bad
Did your groundnut soup or palm nut soup go bad? No need to worry about pouring it all away. Just put it back on fire & drop a piece of charcoal in it. This will extract all the bad taste & smell & restore the soup to its fresh state.

6. Detoxifying
Do you have a hangover out of a drink out with friends the previous night? Just have some charcoal with you & chew on it. To make it more effective, make a nice solution out of it & drink. You’re good to go.

7. Neutralizing Alcohol
If you mistakenly did some wild mixing & feel it can knock you out, just add some charcoal to the mixture & your problem is solved. Or if you took in too much alcohol, just drink some charcoal solution & you’re good to go.

8. Healing Wounds
Do you have a situation where someone’s wound has become so infected to the state doctors are saying they have to cut the affected area? Don’t stress over it, get a large amount of charcoal powder & pour it on the wound. This will extract all the poison from the wound & also help it heal faster. If you have a cut & you want to treat it fast, just get some powdered charcoal & pour on it.

9. Water Filtration
Do you feel your water is contaminated? You don’t need all these products on the market. Charcoal can do better, just drop some amount of it in it. Don’t worry about the colour, it is safe, you can even chew on charcoal. It is far safer than eating chicken from KFC.

10. Skin Cleansing
Do you have pimples, acne or any skin disease you really want to get rid of or do you want a very smooth face or skin? All you need is charcoal. Make a thick solution out of it & smear it on your body & leave it on for some hours before taking your bath. It will leave your skin smooth & fresh.

11. Stain Removal
Do you have some stubborn stain in your kitchen, washroom or on your tiles? You actually need charcoal to get rid of it. I know you’re imagining how this black stainy product can actually remove stains right? Just try it, it works like magic.

12. Getting rid of a Bloated Stomach
If you ate or drank something & feel bloated, charcoal is the best solution to get rid of the bloating.

13. Gets Rid of bad cholesterol
Making a solution out of it & drinking helps eliminate all the bad cholesterol you have stored in you.

14. Ulcer Treatment
Charcoal can treat all ulcers. Just make it a habit to always chew some.

Muhammadu Buhari's Inaugural Speech

Muhammadu Buhari’s inaugural speech.
I am immensely grateful to God Who Has preserved us to witness this day and this occasion. Today marks a triumph for Nigeria and an occasion to celebrate her freedom and cherish her democracy. Nigerians have shown their commitment to democracy and are determined to entrench its culture. Our journey has not been easy but thanks to the determination of our people and strong support from friends abroad we have today a truly democratically elected government in place.

I would like to thank President Goodluck Jonathan for his display of statesmanship in setting a precedent for us that has now made our people proud to be Nigerians wherever they are. With the support and cooperation he has given to the transition process, he has made it possible for us to show the world that despite the perceived tension in the land we can be a united people capable of doing what is right for our nation. Together we co-operated to surprise the world that had come to expect only the worst from Nigeria. I hope this act of graciously accepting defeat by the outgoing President will become the standard of political conduct in the country.
I would like to thank the millions of our supporters who believed in us even when the cause seemed hopeless. I salute their resolve in waiting long hours in rain and hot sunshine to register and cast their votes and stay all night if necessary to protect and ensure their votes count and were counted.  I thank those who tirelessly carried the campaign on the social media. At the same time, I thank our other countrymen and women who did not vote for us but contributed to make our democratic culture truly competitive, strong and definitive.
I thank all of you.
Having just a few minutes ago sworn on the Holy Book, I intend to keep my oath and serve as President to all Nigerians.
I belong to everybody and I belong to nobody.
A few people have privately voiced fears that on coming back to office I shall go after them. These fears are groundless. There will be no paying off old scores. The past is prologue.
Our neighbours in the Sub-region and our African brethren should rest assured that Nigeria under our administration will be ready to play any leadership role that Africa expects of it. Here I would like to thank the governments and people of Cameroon, Chad and Niger for committing their armed forces to fight Boko Haram in Nigeria.
I also wish to assure the wider international community of our readiness to cooperate and help to combat threats of cross-border terrorism, sea piracy, refugees and boat people, financial crime, cyber crime, climate change, the spread of communicable diseases and other challenges of the 21st century.
At home we face enormous challenges. Insecurity, pervasive corruption, the hitherto unending and seemingly impossible fuel and power shortages are the immediate concerns. We are going to tackle them head on. Nigerians will not regret that they have entrusted national responsibility to us. We must not succumb to hopelessness and defeatism. We can fix our problems.
In recent times Nigerian leaders appear to have misread our mission. Our founding fathers, Mr Herbert Macauley, Dr Nnamdi Azikiwe, Chief Obafemi Awolowo, Alhaji Ahmadu Bello, the Sardauna of Sokoto, Alhaji Abubakar Tafawa Balewa, Malam Aminu Kano, Chief J.S. Tarka, Mr Eyo Ita, Chief Denis Osadeby, Chief Ladoke Akintola and their colleagues worked to establish certain standards of governance. They might have differed in their methods or tactics or details, but they were united in establishing a viable and progressive country. Some of their successors behaved like spoilt children breaking everything and bringing disorder to the house.
Furthermore, we as Nigerians must remind ourselves that we are heirs to great civilizations: Shehu Othman Dan fodio’s caliphate, the Kanem Borno Empire, the Oyo Empire, the Benin Empire and King Jaja’s formidable domain. The blood of those great ancestors flow in our veins. What is now required is to build on these legacies, to modernize and uplift Nigeria.
Daunting as the task may be it is by no means insurmountable. There is now a national consensus that our chosen route to national development is democracy. To achieve our objectives we must consciously work the democratic system. The Federal Executive under my watch will not seek to encroach on the duties and functions of the Legislative and Judicial arms of government. The law enforcing authorities will be charged to operate within the Constitution. We shall rebuild and reform the public service to become more effective and more serviceable. We shall charge them to apply themselves with integrity to stabilize the system.
For their part the legislative arm must keep to their brief of making laws, carrying out over-sight functions and doing so expeditiously. The judicial system needs reform to cleanse itself from its immediate past. The country now expects the judiciary to act with dispatch on all cases especially on corruption, serious financial crimes or abuse of office. It is only when the three arms act constitutionally that government will be enabled to serve the country optimally and avoid the confusion all too often bedeviling governance today.
Elsewhere relations between Abuja and the States have to be clarified if we are to serve the country better. Constitutionally there are limits to powers of each of the three tiers of government but that should not mean the Federal Government should fold its arms and close its eyes to what is going on in the states and local governments. Not least the operations of the Local Government Joint Account. While the Federal Government can not interfere in the details of its operations it will ensure that the gross corruption at the local level is checked. As far as the constitution allows me I will try to ensure that there is responsible and accountable governance at all levels of government in the country. For I will not have kept my own trust with the Nigerian people if I allow others abuse theirs under my watch.
However, no matter how well organized the governments of the federation are they can not succeed without the support, understanding and cooperation of labour unions, organized private sector, the press and civil society organizations. I appeal to employers and workers alike to unite in raising productivity so that everybody will have the opportunity to share in increased prosperity. The Nigerian press is the most vibrant in Africa. My appeal to the media today – and this includes the social media – is to exercise its considerable powers with responsibility and patriotism.
My appeal for unity is predicated on the seriousness of the legacy we are getting into. With depleted foreign reserves, falling oil prices, leakages and debts the Nigerian economy is in deep trouble and will require careful management to bring it round and to tackle the immediate challenges confronting us, namely; Boko Haram, the Niger Delta situation, the power shortages and unemployment especially among young people. For the longer term we have to improve the standards of our education. We have to look at the whole field of medicare. We have to upgrade our dilapidated physical infrastructure.
The most immediate is Boko Haram’s insurgency. Progress has been made in recent weeks by our security forces but victory can not be achieved by basing the Command and Control Centre in Abuja. The command centre will be relocated to Maiduguri and remain until Boko Haram is completely subdued. But we can not claim to have defeated Boko Haram without rescuing the Chibok girls and all other innocent persons held hostage by insurgents.
This government will do all it can to rescue them alive. Boko Haram is a typical example of small fires causing large fires. An eccentric and unorthodox preacher with a tiny following was given posthumous fame and following by his extra judicial murder at the hands of the police. Since then through official bungling, negligence, complacency or collusion Boko Haram became a terrifying force taking tens of thousands of lives and capturing several towns and villages covering swathes of Nigerian sovereign territory.
Boko Haram is a mindless, godless group who are as far away from Islam as one can think of. At the end of the hostilities when the group is subdued the Government intends to commission a sociological study to determine its origins, remote and immediate causes of the movement, its sponsors, the international connexions to ensure that measures are taken to prevent a reccurrence of this evil. For now the Armed Forces will be fully charged with prosecuting the fight against Boko haram. We shall overhaul the rules of engagement to avoid human rights violations in operations. We shall improve operational and legal mechanisms so that disciplinary steps are taken against proven human right violations by the Armed Forces.
Boko Haram is not only the security issue bedeviling our country. The spate of kidnappings, armed robberies, herdsmen/farmers clashes, cattle rustlings all help to add to the general air of insecurity in our land. We are going to erect and maintain an efficient, disciplined people – friendly and well – compensated security forces within an over – all security architecture.
The amnesty programme in the Niger Delta is due to end in December, but the Government intends to invest heavily in the projects, and programmes currently in place. I call on the leadership and people in these areas to cooperate with the State and Federal Government in the rehabilitation programmes which will be streamlined and made more effective. As ever, I am ready to listen to grievances of my fellow Nigerians. I extend my hand of fellowship to them so that we can bring peace and build prosperity for our people.
No single cause can be identified to explain Nigerian’s poor economic performance over the years than the power situation. It is a national shame that an economy of 180 million generates only 4,000MW, and distributes even less. Continuous tinkering with the structures of power supply and distribution and close on $20b expanded since 1999 have only brought darkness, frustration, misery, and resignation among Nigerians. We will not allow this to go on. Careful studies are under way during this transition to identify the quickest, safest and most cost-effective way to bring light and relief to Nigerians.
Unemployment, notably youth un-employment features strongly in our Party’s Manifesto. We intend to attack the problem frontally through revival of agriculture, solid minerals mining as well as credits to small and medium size businesses to kick – start these enterprises. We shall quickly examine the best way to revive major industries and accelerate the revival and development of our railways, roads and general infrastructure.
Your Excellencies, My fellow Nigerians I can not recall when Nigeria enjoyed so much goodwill abroad as now. The messages I received from East and West, from powerful and small countries are indicative of international expectations on us. At home the newly elected government is basking in a reservoir of goodwill and high expectations. Nigeria therefore has a window of opportunity to fulfill our long – standing potential of pulling ourselves together and realizing our mission as a great nation.
Our situation somehow reminds one of a passage in Shakespeare’s Julius Ceasar
There is a tide in the affairs of men which,
taken at the flood, leads on to fortune;
Omitted, all the voyage of their life,
Is bound in shallows and miseries.
We have an opportunity. Let us take it.
Thank you
Muhammadu Buhari
President Federal Republic of NIGERIA and
Commander in-chief-of the Armed forces

Second Chance Crooner: Mexican actress Lorena Rojas dies of cancer aged 44

Lorena RojasLorena Rojas died less than a week after her 44th birthday
Lorena Rojas, a popular Mexican actress who starred in more than a dozen soap operas, has died aged 44 following a lengthy battle with cancer.
She was diagnosed with breast cancer in 2008 and became an advocate for cancer education in Latino communities.
The actress passed away at her home in Miami. Her last message to her fans was sent on Twitter less than a week ago.
In the birthday message, she wrote: "Thank you all for celebrating my birthday with me. Beautiful day."
Rojas starred in such acclaimed Spanish soaps as El Cuerpo del Deseo, Pecados Ajenos, Alcanzar Una Estrella and, most recently, the series Demente Criminal.
Lorena RojasThe actress' agent praised the 'fans who she loved until the end'
She also appeared in films such as Manos Quietas and Aventurera.
In addition, the actress wrote and recorded an album of children's music called Hijos del Sol, which was inspired by her daughter Luciana.
Rojas was initially thought to have made a recovery after her original breast cancer diagnosis. But in 2012 she was told her cancer had spread to her bones, and last year the tumour spread to her liver.
Her boyfriend, family and friends were by her side when she died, her agent Latin WE said.
A statement from Latin WE said: "Lorena takes a step into eternal life leaving as her greatest legacy the love for animals and for art in all its forms, her tender devotion to her daughter, her passion for life, the appreciation of all her Lobitas and fans who she loved until the end."
